As a general rule, when a roadway is platform l i: is secured to the rear side of the covered with broken or crushed stone, ruts rear axle beam and stands outwardly soon will be formed therein by vehicles iol suitable distance for the support of an oplowing' the same track, and ii' immediate and orator or person Who controls the Severa 7 proper care of the road surfaceiis not taken, mechanisms of the machine.

proposed to use any kind of material 'n the cross rod :42 loosely carried at opposite ex- '1 formation of the ame. The frame 5 is trennt ies in or similar devices 23 atsuitably mounted on transverse axle beams tached to a short cross beam 2% having an and 7 respectively located below the eye secured to its "front side at the center and GXilEZIDltlQS of the "frame and havthereof and by an eye-bolt pro jecting rearwardly from the beam 11. Depending from the inner portion of each of the side beams of the frame 5 is ahanger 27 having a lower hooked end to engage under and intermediately sustain the adjacent rod 22. The beams 24 are loosely connected in the manner just explained throughv the medium of the eyes 25 to permit these beams to be rocked or canted to correspondingly adjust-theblades 16 and 17, and in addition to this adjustment the blades through the carrier rods 18 may also have a hinge action. By connecting the beams 24 to the beam 11 through the medium of the eyes 25 and 26, stiffness of action during the adjustment of the carrier rods 18 and the blades or plates 16 and17 is avoided, and through the devices which will be hereinafter specified the blades arerendered sensitive to varying adjustments in scraping the road covering of broken or crushed stone or any other material with which the blades may be brought into engagement.

The rear adjusting beams 20 are suspended below the frame 5 through the medium of angle plates or strips 2"? secured thereto and having outer upwardly projecting angular extremities 28 movably attached by links 29 to bell crank levers 30 pivoted against the inner sidesof the side beams of the frame 5 and having their upper extremities connected by rods. 31 to operating levers 32 having suitable catch means working in conjunctionwithadjustment-retaining devices or toothed segments 33. The angle plates or strips 2? are mounted on the beams 20 in such manner as to have a slight swinging movement, the means employed to permit this latter movement for each of the beams being a single fastening means 34 being inserted'through the centers thereof and into each of the said beams 20, as shown by Fig.

1, in order to prevent stiffness of these angle plates during the adjustment, and par ticularly when the blades 16 and 17 and their carrier rods 18 together with the beams 20 are unitedly shifted laterally or in opposite sidewise directions. The inner extremities of the angle plates 27 are upturned,

as at 35 and36, and connected to these two inner extremities is a link 37 whereby the beams 20 and the blades 16 and 17 and rods 18 will be heldaparta uniform distance in accordance with a predetermined adjustment and also shifted as a unit in lateral directions. The means for shifting the beams 20 and the blades 16 and 17 together with the carrier rods, 18 in opposite sidewise directions consists of a connecting rod 38 attached to the one upward angular projection 36 at the inner end of one of the angle plates 27 and also attached to a horizontal bell crank lever 38 fulcrumed against the lower side of the ad acent side beam of the frame 5. An actuating connecting rod 39 is also attached to the bell crank lever 38 and to an operating lever 40 at one side of the rear of the frame and held on the cross beam 15, which also supports the segments 33. Adjacent the lever 40 is a toothed segment 41 with which a suitable catch dog 42 carried by the lever 40 cooperates to maintain the lateral or sidewise adjustment of the blades as may be desired.

A U-shaped bracket 42 is secured to the beam 11 and has the arms thereof extending upwardly, and to these arms bell crank levers 43 and 44 are pivotally attached. To the lower arms of these bell crank levers 43 and 44 links 45 and 46 extend down-- wardly and are movably connected to the inner extremities of the beams 24 to which the forward ends of the carrier rods 18 are attached by the cross rods 22. To the upper arms of the bell crank levers 43 and 44 connecting rods 47 and 48 are respectively attached and also movablysecured at their rear ends to levers 49 and 50 sup'portedjby and adjacent to toothed segments 51 and 52 and provided with suitable catches to inter lock with said segments. The segments 51' and 52 are mounted on the cross beam 52 and the rear end of the frame to which the axle beam 7 is attached. The levers 49 and 50 are shiftable forwardly and rearwardly to correspondingly shift the connecting rods 47 and 48 and operate the bell crank levers 43 and 44to lower or raise the inner ends of the beams 24, which readily swing, in view of the eye-bolt connections 25 and 26 therefor, relatively to the beam 11. By swinging the beams 24 in the manner just explained, the carrier rods 18 and blades 16 and 17 are correspondingly adjusted at angles to the road surface, and whereby the crown of the road may be given the desiredangle or pitch.

Depending from the rear axle beam 7 are a pair of hangers 53, as'clearly shown by Fig. 3, and movably attached to these hangers is a rear leveler 54 having arms 55 through which and the lower extremities of the hangers extends a pintle or rod 56. The

leveler 54 is of su'l'licient weight to perform the function for which it has been devised and applied to the machine, namely, to level the ridge which is sometimes producedby' operate on opposite side portions of the covering of the roadway. Moreover, by operating the devices hereinbefore specified, the blades 16 and 17 can also be disposed to have their inner lower corners elevated or their outer corners lowered, or vice versa,

in accordance with the work to be performed, or to produce the desired shape of the road surface. The leveler 5% following behind the blades 16 and 17 will insure a flattening of any ridge that may be produced by the blades 16 and 17. It will be seen that all of the adjusting levers are located adjacent the platform 14 within easy reaching distance of an operator and may be quickly manipulated to dispose the blades 16 and 17 as may be required during the operation of working the covering of the road bed. The scraper blades are so mounted and have such adjustment that both the outside of the road covering as well as the center portion thereof may be easily reached and worked, and the ruts will be quickly filled in by the action of the scraper blades and the surface of the road covering given a level and properly pitched form. The parts may also be modified in proportions and general dimensions to adapt the machine to various kinds of work, as for instance, by lengthening the two connecting rods between the scraper blades and permitting a greater lateral shifting action of the said blades, the latter may be practically used to fill a tile ditch or level up a land furrow.

In addition to the uses of the machine as hereinbefore specified, it will be understood that it can be employed for any other work to which it may be adapted.
